Specificationof Letters Patent.

Application filed August 3. 1905. Serial No. 272,462.

T 0 all whom it may concern:

Be it known that l,- Enwann L. AIKEN, a citizen of the United States, residing at East Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Im rovements in Phonographs, of

. may beapplied to or removed therefrom.

My invention has for its object the provision of an improved form of locking latch for holding the end gate in its closed position and consists in the features hereinafter set forth and claimed.

Reference is hereby made to the accordpanying drawings in which Figure 1 is a front elevation showing my invention applied to a phonograph. Fig. 2 is an end elevationof the same, and Fig. 3 is a detail view partly in section of the looking latch.

The phonograph shown is of the usual type comprising a frame or body 1 which supports a rptating'tapering mandrel 2 upon W ich a cylindrical sound record 3 may be carried, the reproducer (not shown) being carried in an eye 4 of a traveling carries arm 5, which. is supported and driven in the usual manner.

The end gate 6 is pivoted on a'vertical pin 7 carried by the boss 8 projecting from the frame 1, so that it can be turned from the position shown in Fig; 1 through an arc of 90" degrees or more to completely expose the end of the mandrel 2 and permit the record 3 to be withdrawn therefrom. The end gate 6 is provided with a pivot pin 9 passing therethrough, and held in place by a screw 10 having a collar 11 engaging a slot in the pin 9. The pin 9 isso placed as to engage the center of the head of the mandrel to form a 'vot bearing therefor. All'the parts which]: ave

thus far described are of well known construction. V I

In order to hold the end gate firmly in its closed position, and at the same time to readily release the same Whenever'desired, 1 pro "stead of the arm 17.

vide a locking latch 12 which turns freely about a screw 13 which is threaded into the frame 1, the axis of the screw being parallel to the'am's of the man drel.. Within the body,

of the latch 12 is formed a cup 1 1 which surrounds the screw 1.3 and contains a coil spring 1.5 whose ends abut against the bottom of the cup and the head of thescrew 13; One endof the latch 12 is enlarged into afingerfpiece 16 and the opposite. end into a short arm 1 7 for engaging the end gate.

The end. gate is provided with a recess 18 into-which the arm 17 passes when the finger piece 12' is moved downward. When the finger piece is moved upward, the arm;17 passes out of engagement with the end gate andpermits the same to be opened. Theventing any possible play of the end gate on its ivot. Obviously the cam surface may, if esired, be placed upon the end gate in- Having now described my invention, what I claim as new and desire to secure by Letters Patent is as follows! 1. In a phonograph, the combination with the frame or body, rotating mandrel. and pivoted end gate carrying a bearing for the outer end of the mandrel and provided with a recess, of alocking latch, a pin carried by the frame upon which said latch is pivoted on an axis substantially parallel to the axis of .the mandrel, a spring cooperating with said pin to press against said latch, and a, projection extending from said latch in po'-- sition to engage the recess of said end gate and hold it in its closed position, one of said engaging parts being provided with a sloping cam surface for causing the latch to compress the spring and thereby hold the end gate in position under pressure, substantially as set forth.

2. In a phonograph, the combination with the frame or body, rotating mandrel and pivoted end gate carr ing a bearing for the outer end of the mandi'el' and rovided with a recess in its lower surface, 0 a pin carried by said body and substantially arallel to for operating said latch, substantially as set the axis of the mandrel, a 100 ing latch forth.
